irregular gears, the gear 57 being fixed to theshaft 46 of the female folding cylinder the gear 58 being fixed to the shaft '59 of the transfer cylinder 13. The feedroller shaft 60 for thecylinder 13 is provided with a gear 61 which meshes with a gear 62 fixed to the shaft 59 of the transfer cylinder 13.

Sheet pressure rollers (33, 04, 65, 66 engage the peripheries ofthe cylinders 4, 9, 3 and- 11 respectively, for holding the sheets against the peripheries of these cylinders when the sheets are disengaged from their grippers. Carrying tapes G7, 68 are arranged to convey the assembled and folded group of press, insert and cover sheets from thefemale folding cylinder 4 through slitters 69, 70, to a predetermined point, such, for instance as a collecting pocket carrier 71 like that shown in my United States Letters Patent No. 749,362 dated January 12 1904.

The insert offset roll 29 is driven from the gear 45 of the cylinder 4, through'the train of gears 72, 73, 73*, 74, 75, 76, 76*, shaft 77 and train of gears 77*, 78, 79, 80, 31. The I cover offset roll 38 is driven from the gear 72 through a train of gears 73, 73**, 84, 85, 86, 87, 88. The rotary cutters 17, 18, are driven from the gear 45 through a train of gears 89, 90, 91, 92, 93, and the rotary cutters 24, 25 are driven from the gear 91 through a train of gears 94, 95, 96, 97 98.

The rotary cutters 33, 34, are driVen tom the gear through a train of gear-s99, 100, 101. The Web feeding tapes 23, 16 M16132 are driven from their respective cutters by suitable gearing which neednot be speci-fi-ically described. The set of grippers 10 on the sheet collecting cylinder 9 is opened every revolution to receive the advance'edge of a sheet from-themainpress by means of a fixed cam 102 which engages the gripper lever 103 at thev The set of grippers 10 isopened every second revolution of the cylin; der 9 to transfer a collected group of, two

The set of grippers 12 on the, in; sert sheet transfer cylinder 11 is opened;

every revolution to receive the advanceedge of a sheet from the cutters 24, 25, by a sta, tionary cam 109 which is arranged nposrg by means of a fixed cam 111 which engages the lever 110 at the proper point.

120;; tion to engage the gripper opening lever -1 at the required time. 'This set of grippers v 12 is opened every revolution of the cylinder. 11 to transfer the insert sheet to the set Off grippers 5 on the male folding cylinder-3,5125,

The set of grippers 14 on the cover sheet transfer cylinder 13 is opened to receive the? advance edge of the cover sheet as it leaves the guides 35, 36, by means of a fixed cam 112 which is arranged in position to engage the gripper opening lever 113 at the proper time. Another fixed cam 114 is arranged in -position to engage the lever 113 at the proper time to transfer the advance edge of the cover sheet from the set of grippers 14 to the set of grippers Ton the female folding cylinder 4.

A fixed cam 115 is arranged in position to engage the openinglever 116 ,of the set of grippers 7, at the proper time to receive the advance edge of the cover sheet from the set of grippers 14. A second fixed cam 117 is arranged in position to engage the lever 116 of the set of grippers T at the proper time to transfer the advance edge of the cover sheet to the set of grippers on the male folding cylinder 3. i

A fixed cam 118 is arranged in position to engage the opening lever 119 of the set of grippers 5 on the male folding cylinder 3 at the proper time to receive the advance edge of the insert sheet from the transfer cylinder 11. A second fixed ram 120 is arranged in position to engage the lever 119 at the proper time to open the set of grip pers 5 to receive the collected group of two sheets from the main press. A third fixed earn 121 is arranged in position to enga e the lever 119 to open the set of grippers 5 to receive the ad 'ance edge of the, cover sheet from the set of grippers 7. A fourth fixed cam 122 is arranged in posit-ion to env gage the lever 119 to open the set of grippers 5 to release the advance edges of the assembled group of sheets at the proper time of folding the same from the male folding cylinder on to the female folding cylinder.

The coaction of the folding devices on the cylinders 3 and 4 is obtained as follows: A fixed box cam 123 is arranged to control the floating movement of the blade (3 through the truck roller 12% and a cam 125 is arranged to control the tucking movement of the said blade by its engagement with the stud roll 126. A fixed box cam 127 is arranged to control the floating of the folding jaws by its engagement with the truck roller 12S and a fixed cam 12!) is arranged to control the opening, of said jaws by its cngagement with the stud roll 130. The opening of the floating jaws to release the folded signature at. the proper time to permit it to be fed between the tapes (3?. 8 is contri'illcd by a stationary (am 131 which engages the stud roller 130".

The movements of the parts hcrcinabove described are so timed with respect to each other. that the rotary cutters 1T. 18. and the sheet collecting cylinder 5) complete two revolutions to one revolution of the folding cylinders. The rotary cutters 2 25. for the insert web and their transfer cylinder 11,

rot-ate one revolution for one revolution of the folding cylinders so that one insert. sheet is transferred to the male folding cylinder for two-sheets from the main web delivered from the collecting cylinder 9. The irregular gears 51, 52, are so shaped that the grippers 12 will be caused to travel at the speed of' the insert web at the time of engaging the advance edges of the insert sheet and will be caused to travel at the surface speedof the male folding cylinder at the time that the advance edge of the insert sheet is transferred to the grippers 5. The rotary cutters 33, 34, for the cover web and their transfer cylinder 13, complete one revolution for every revolution of the folding cylinders. The irregular gears 57, 58 are so shaped that the cylinder 13 will be caused to travel at the speed of the cover web at the time the grippers 14 engage the advance edge of the c ver sheet and at the surface speed of the female folding cylinder 4 at the time that the advance edge of the cover sheet. is transferred to the grippers 7.

1n,the form shown in Figsz l to (3 ill-- clusive, the insert sheets cut and fed from the source of insert supply are associated with, the collected sheets cut and fed from the main press web at the same point in the width of the sheets as the sheets cut and fed from the source of cover supply, the cover sheets being fed to one side of the collected group of sheets from the press and the insert sheets being fed to the other side of the collected group. In these figures at single cover sheet and a single insert sheet are shown as combined with the first. group of collected sheets from the press in the completed signature and the other three groups of collected sheets from the main press are shown as being successively dcposited within the so assembled group of cover. insert and main press shorts,

While I have shown the cover sheets and insert sheets as combined with the first group of collected sheets from the press in the completed signature. it is evident that these cover and insert sheets may be combined in any other manner with any of the four groups of collected sheets from the main press, by shifting the insert and cover sheet web rolls to any desired positions on their shafts laterally with respect to the machine.

In the form shown in Fig. 7, an extra insert web roll 22"" is shown as mounted on the cover web roll shaft in such a position that it will be interposed between the second and third collected groups of sheets cut and fed from the main press web.

In Fig. 8, an extra insert welt: roll 22*: is so mounted on the shaft of the insert web roll 22 that it will be interposed between the third and fourth collected groups of sheets cut and fed from the main press web;

lroceeding to describe the operation of i the collectedgroupof sheets.

the machine in the form shown in Figs. 1 to 6 lncluslve in which a completed s1gnature 1s formed having one cover and one insert sheet combined with four groups of.

collected sheets from the main press, .as in the manner illustrated in Fig; 9, the cutters 24, 25, cut successive sheets from the insert web and feed them between the guides 26,

engaged by thegrippers i l on thetransfer' cylinder 13. One cover sheet is transferred to the grippers 7 of the female folding cylinder 4 every revolution thereof when the grippers 7 and 14 are brought together. The rotary cutters 17 18, which are driven at twice the speed of the cutters for the insert and cover sheets, sever sheets frcm the web fed from the main press and feed them down between the guides 19 and 20; The collecting cylinder 9 is arranged to have its-grippers 10 collect two sheets thereon and then transfer the two sheets to the grip pers5 on. the male folding. cylinder 3 when the said grippers come together. As the grippers 5 and 7 on the two folding cy5in ders come together, the cover sheet on the female folding cylinder will be transferred to the male cylinder, the grippers 5 on the male cylinder then engaging the advance edge of one insert sheet, two sheets from the main press and one coversheet. As the folding mechanism of the two cylinders 3 and 4 is brought into coaction, the grippers 5 are opened to release'ihe advance edges of The assembledtcover, main pressand insert sheets are brought down between the tapes 67, (38 and the jaws 8 of the folding mechanism are openedto permit the tapes 67 68 to feed the collected sheets between the slit-ters 6t), 70,

from whence the completed collection of sheets dropsdnto the pockets on the carrier 71.1. After thefourth successive movementof the pocket carrier 71, a completed signature will be delivered each step of the car'- rier with'thc sheets so combined'that there will be a cover sheet, two main press sheets, an insert sheet and three collected groups of twomain press sheets in each completed signature.

It'can be readily understood that instead v of"transferring the advance edge of the to the'cylinder 3 but will be fed between the folding cylinders and have its advance edge releasedfrom the grippers 7 in ample time to permit the assembled insert, main web and cover sheets to be folded together and fed between the tapes 67, 68.

It will be seen that the machine as hereinabove set, forth accomplishes the assembling and folding together of sheets from the main'press and from the insert and cover supplies without the -necessity of employing formers, turning-harem carrying tapes. It is evident that various combinations of insert sheets within the collected groups of main press sheets in, the completed signature may be accom lished by varying the number of insert we supply rolls and varying the positions of the. rolls on both 'the insert Web. roll shaft and on the cover Web roll shaft; It will also be seen from the above descri tion that one or more insert sheets cut an'c fed from a previously printed source of insert supply may be combined with the sheets cut and fed from the main press web, and the sheets cut and fed'froin the source of sheet supply in such manner that the insert sheet or' sheets may be located at any desired point or points within the completed signature, this result being accomplished by the ability to feed the insert sheets to different points in the width of the main Web sheets and from both ends of the machine so that the insert sheet-s may occupy positions upon either. side of the several collected groups of main press sheets which go'to form the complete signature.
